Abstract

L'invention concerne un système vidéo de projection par laser et un écran holographique. Le système comporte un système d'images vidéo à laser pulsé équipé d'un écran holographique pour recevoir les images vidéo en couleurs, l'écran étant doté d'une couche holographique (couche 1) destinée à réfléter en retour les images vidéo en couleurs vers le spectateur, et à transmettre à travers l'écran la lumière ambiante en vue de produire des images vidéo à grand contraste.
